Abstract
A magnetic disk medium allows embedding ID information that prevents manipulation and yet holds its uniqueness. ID information for uniquely identifying a medium is recorded separately as a master ID information on a preformatted region and as individual medium ID information on a non-preformatted region in a pre-embossed type magnetic disk.
